ColoradoKote
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.

Three Stages of Conversion Coating
Precise chemistry control at every step ensures uniform oxide formation and consistent corrosion protection across every lot.
Multi-Stage Surface Decontamination
Parts move through alkaline cleaning and acid deoxidizing to remove oils, oxides, and handling contaminants. Rinse water conductivity is verified below 10 microsiemens per centimeter between each step to prevent cross-contamination of the conversion bath.

Controlled Chemical Reaction
Parts are immersed in MIL-DTL-5541 conversion solution at 70-90 degrees F for 2-5 minutes. Solution concentration is monitored daily through titration. Temperature is held within 5 degrees F of specification to ensure uniform oxide layer formation.

Deionized Water Rinse and Inspection
Multi-stage deionized water rinses remove all residual chemistry. Visual inspection confirms uniform coating color and coverage. Coating weight is measured at 40-100 mg per square foot to verify specification compliance before release.


The Chemical Conversion Coating Process
Chemical conversion coatings create a thin oxide layer on aluminum that improves corrosion resistance and promotes adhesion for subsequent coatings. ColoradoKote processes Type I and Type II formulations under AS9100 protocols with full solution monitoring and lot traceability.
What Our Conversion Coating Delivers
Process parameters are monitored, recorded, and traceable to each lot for complete quality documentation.
Hours Salt Spray Resistance
Type I Class 1A conversion coating delivers 168+ hours of salt spray resistance per ASTM B117. The protective oxide barrier guards against moisture, salt spray, and galvanic contact on aluminum alloys including 2024, 6061, and 7075.

Full Lot Traceability
Solution concentration, temperature logs, immersion times, and visual inspection results are recorded and traceable to each lot number. Your Certificate of Conformance contains all process parameters and coating weight measurements.
Coating Thickness
Conversion coating forms at under 1 micron thickness, creating zero dimensional change to machined parts. Thread fits, bearing surfaces, and mating components remain unaffected while gaining corrosion protection and enhanced coating adhesion.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Yes. OEM brand colors for aircraft interiors, avionics housings, and equipment panels require documented, repeatable color standards. We capture the target color by spectrophotometer, develop the Cerakote match to Delta E 1.5, and lock the formulation and process parameters into our AS9100 system. Every subsequent order is verified against the original standard. This ensures your brand color is consistent across parts, programs, and years.
Yes. Fertilizers, herbicides, and pesticides contain aggressive chemical compounds that attack conventional paint and powder coat finishes. Cerakote's ceramic-polymer chemistry resists this chemical attack while maintaining color stability. ColoradoKote verifies color hold through chemical exposure as part of our quality process. For sprayer components and chemical application equipment, Cerakote provides both chemical protection and lasting color identification that conventional coatings cannot maintain in agricultural chemical environments.
AM parts require specialized blast parameters due to their inherent surface roughness and often delicate geometries. We blast SLS, MJF, and metal AM parts at 40-60 PSI, which reduces surface roughness from Ra 8-15 micrometers toward a more uniform profile without damaging lattice structures or thin walls. This controlled preparation is the foundation for Cerakote to reduce final surface roughness below 3 micrometers while adding corrosion and wear protection.
Defense electronics housings require coatings that protect against corrosion and field conditions without altering dimensions on mating surfaces, EMI gasket channels, and connector interfaces. Cerakote's 0.5 to 2 mil film build maintains these critical tolerances where powder coat's 4 to 6 mils would require masking or post-machining. Less coating mass also reduces weight on man-portable electronics and UAV-mounted systems.
Yes. Biofouling residue, salt crystal deposits, and marine corrosion products are effectively removed by ultrasonic cavitation combined with appropriate cleaning solution chemistry. The cavitation action breaks down biological films and mineralized deposits that resist manual scrubbing and solvent cleaning. For marine hardware being recoated, complete removal of biological and salt contamination is critical for coating adhesion and long-term corrosion protection in continued marine service.
